After “crossing paths” with the other Tusk band members — who were playing out together covering Fleetwood Mac songs and “singing them incredibly well” — someone suggested the idea of a tribute band.

“And here we are today,” said McDonald.

It was a suggestion that definitely worked.

“It’s very much a theatrical show,” he said.

During a typical Tusk show, the band covers all of Fleetwood Mac’s greatest hits. But, they also play the roles of Fleetwood Mac’s band members Mick Fleetwood, Christine and John McVie, Lindsey Buckingham and Stevie Nicks.

“We look at their styles and emulate that period of around the late 1970s,” said McDonald. “We have a backdrop taken directly from one of their shows ... let’s just say we’re committed.”

And they’re also committed to playing all of the songs Fleetwood Mac fans clamor for.

“Fifteen to 20 songs, we have to do almost every time,” he said. “And we do three different songs every show to change it up a bit.”

A few songs are an absolute must, though.

“We have to sing ‘Rhiannon’ and ‘Go Your Own Way.’ If we don’t the audience will rise up like an angry mob,” McDonald said with a laugh. “Which we would probably deserve.”

Right now, Tusk doesn’t have a CD out. But they are “in the process” of putting together a live album that will be released at the end of this year, McDonald said.

McDonald, who’s often told he sounds a lot like Buckingham, never tires of listening to — or playing — the music of Fleetwood Mac.

“I have all of their songs on my Nano and not a single day goes by that I don’t listen to them,” he said. “I don’t get tired of hearing them and I don’t get tired of playing them either. Being a part of this band, it’s the most fun I’ve ever had musically.”
